PROBLEM TO BE SOLVED: To provide an image forming device capable of detecting whether or not an incommunicability is caused on a specified developing cartridge side when the specified developing cartridge and a control means can not communicate with each other. SOLUTION: Non-volatile memories functioning as an identification means are respectively provided in respective cartridge 231 to 234, and developing side connectors 24 are respectively provided in the respective non-volatile memories. In the case of judging that the non-volatile memory of the 1st cartridge 231 and a CPU can not communicate with each other, whether or not the non- volatile memory of the 2nd cartridge 232 and the CPU can communicate with each other is judged. Therefore, operation can be compared between the 1st and the 2nd cartridges 231 and 232, and whether or not an incommunicability is caused on the 1st cartridge 231 side is detected. |
